Public WiFi connections are often unsecured, leaving their connections open to being hijacked or “sniffed” by malicious people. To protect users from data and privacy loss due to insecure and untrusted connections, web sites and applications are increasingly being run entirely over secure connections (HTTPS).
My prediction is that by 2015, it will be bad practice to access web sites via HTTP, and users will increasingly demand HTTPS. This has interesting implications for hardware manufacturers and software development teams alike.
